NADPH and ferredoxin:NADP+ oxidoreductase-dependent reduction of quinones and their reoxidation

Molecular oxygen uptake was initiated by adding NADPH (1 mM) to the buffered medium containing 0.6 μM spinach ferredoxin:NADP+ oxidoreductase and 20 μM quinone (plastoquinone-2, decyl-plastoquinone, decyl-ubiquinone, or duroquinone). At pH 7.7 the rate of oxygen uptake was 2- to 12-fold higher during an initial phase (V1) than in a subsequent phase (V2). Except for duroquinone, the initial rate of oxygen consumption was ca. 2.7-fold higher in alkaline than in acidic medium. Ferredoxin was not essential, although it stimulated the reaction investigated. Oxygen uptake was not detectable with plastoquinone-9 or α-tocoquinone. The possible mechanisms of the NADPH and ferredoxin:NADP oxidoreductase dependent reduction of some quinones and their reoxidation are discussed.
